Police in Canada are looking for the driver of a black Ford Focus who side-swiped a silver sedan on the northbound Highway 410 in Mississauga, Ontario a few days ago.

Footage of the incident was shared on Twitter through the official Ontario Provincial Police account and shows just how quickly an erratic driver can put the lives of other motorists at risk.

The video starts by showing a black Ford Focus slowly passing the car with the dashcam and approaching a silver sedan. Eager to overtake the sedan, the Focus driver aggressively moves over to the right, accelerates past the sedan, and then swerves in front of it. The Focus driver then brake checks the sedan, resulting in a minor rear-end collision that sent the latter fishtailing down the road.

What’s particularly disturbing is that the Focus driver can be seen fleeing the scene as if nothing had happened…

A look at the Twitter thread in the Ontario Provincial Police’s tweet reveals that many other Canadians see instances of similarly dangerous driving on Highway 410 on a frequent basis.

Making the incident all the more worrying is the fact that the sedan was traveling in the high-occupancy vehicle lane (HOV lane), a lane dedicated to vehicles with at least a driver and one or more passengers onboard. Not only was the driving of the Focus very dangerous but it was also illegal. Here’s hoping the video will help the authorities identify the culprit.
